I used this cable to interconnect my newly purchased Surface Pro to a Dell 22″ monitor running 1680 x 1050 resolution. It worked great! And, unlike the Microsoft adapter it is long enough to span between the monitor and tablet without having to buy an extension cable. So, I have one cable at about one third the price.

Ordered this to hook my MacBook Air up to an external NEC monitor from a few years ago. Came very quickly, feels sturdier workmanship than many of the cables you’ll find out there. The Thunderbolt port fits smoothly without blocking the USB port beside it. And the VGA connection to my monitor works, too. For those of you with an old VGA-only monitor, this is a good deal.
